I have a 2000 F250 7.3 pulling a 10K 5th wheel. It was a little weak and I called Mike who made recommendations for an upgrade. I had my own ideas but Mike had done hundreds of these upgrades and showed me my error in thinking. I am so happy with his expertise, his customer relation skills, his technician who did the work. I had the truck chipped, up pipes, turbo, and and oil link all done in one day. Truck performs beyond my expectations. Thanks Mike. - Bryon G. (5 star review on Yelp)
